The snake family Viperidae is divided into two subfamilies by the presence or absence of pit receptors. The Viperinae, found throughout Europe, Africa and Asia, apparently lack any form of infra-red receptor (Bullock & Barrett, 1968). The Crotalinae, instead, are characterized by the presence of a highly specialized pit receptor in the loreal region of either side of the face. Five principal ge...

No fewer than 39 species of dangerously venomous snakes are currently known to inhabit Myanmar and the adjacent coastal waters. Of these, 15 are sea snakes and except for two, Laticauda colubrina and Laticauda laticauda, none voluntarily come onto land (occasionally, obligate marine species may be carried onto shore during severe weather by wave action or enter river deltas in brackish water). ...

Tropidolaemus wagleri and Cryptelytrops purpureomaculatus are venomous pit viper species commonly found in Malaysia. Tandem mass spectrometry analysis of the crude venoms has detected different proteins in T. wagleri and C. purpureomaculatus. They were classified into 13 venom protein families consisting of enzymatic and nonenzymatic proteins. Enzymatic families detected in T. wagleri and C. pu...

# 2002 International Union of Crystallography Printed in Denmark ± all rights reserved The crystal structure of TM-3, a small snake-venom metalloproteinase (SVMP) isolated from Taiwan habu (Trimeresurus mucrosquamatus), was determined at 1.35 AÊ resolution with resultant R and Rfree values of 0.181 and 0.204, respectively. The overall structure of TM-3 is an oblate ellipsoid that contains three...
